Is it possible to map bottom hardness using your software ?

Yes, this is possible, however this feature is not supported for all echosounders.

For Hydromagic to calculate the bottom hardness, you need echosounder hardware which is capable of:

• Return reflectivity;
• Return bottom-loss;
• Return multiple return signals (E1 and E2);
• Return depth for two frequencies.

If your hardware meets one of these requirements, please contact support for more information.
